Is there any way to get at a result set that only has one entry when using

Question

And please dont tell me its because of the driver... I know this but cant do anything about it
Using Access the only method available is rs.next() and I think that when the statement is prepared it goes to the first (and only) row, so when it executes the cursor is in the wrong place....
Maybe someone could show me some code that stores the rs in somethingI can search through... Theres been some mention of vectors and hashtables but I've not used them (yet)!
String fName = "empty";
String query = "SELECT * FROM Committee WHERE UName LIKE ?";
java.sql.PreparedStatement statement = connection.prepareStatement(query);
statement.setString(1,user);
java.sql.ResultSet rs = statement.executeQuery();
while (rs.next())
fName = rs.getString("FirstName");
out.println("first: " + fName);
This prints nothing
However when I use:
java.sql.Statement statement = connection.createStatement();
java.sql.ResultSet rs = statement.executeQuery(""SELECT * FROM Committee WHERE UName LIKE 'pippip' ";
It does!
The user variable is printed onto the page to test it exists -which it does
And it cant be sending null to the database or else I'd get a null pointer or sql exception...
Its driving me nuts!!!

Like is only used when you want to compare approximate values using wild cards.
You however are not using wildcards.
If you want to do an exact match then you should use '='. If you want to approximate matches then you should use a wildcard: '%' or '_'.
java.sql.PreparedStatement statement =
connection.prepareStatement(query);
statement.setString(1,user);
java.sql.ResultSet rs = statement.executeQuery();
while (rs.next())
fName = rs.getString("FirstName");
out.println("first: " + fName);
